CO2 won't work for bret, the L has a water to air IC, there just isn't anyplace to spray it.
bret, if this is just for track duty, i would just ice down the s/c and intake manifold before each run, and maybe throw some ice in the IC coolant bottle (lemme check on that ice in the bottle thing, just to make sure it won't screw up the pump or something, lol)
some NO2 across the intercooler would be pretty helpful for charge cooling too
